Dry-pipe sprinkler valve maintenance checklists for the quarterly and annual rounds: 2 free lists, 11 items and 16 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against NFPA 13 and NFPA 25; the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Dry-pipe sprinkler valve quarterly maintenance checklistquarterly
- Every quarter, and watched most closely heading into cold weather since the enclosure heat is what keeps the valve from freezing and false-tripping. Run by: The building engineer or sprinkler service tech reading the gauges and the enclosure on the quarterly round, recording conditions rather than tripping the valve.
- Dry-pipe sprinkler valve annual maintenance checklistannual
- Once a year, coordinated with the technician and the monitoring station placed on test, timed so the system can be dried, reset and returned to service the same day. Run by: The facilities lead witnessing the sprinkler technician's annual trip test and recording the observed times and pressures, while the technician performs the test and resets the valve.
What most often fails on a dry-pipe sprinkler valve
- System air and water gauges read individually but never compared, so a differential that has crept toward the trip point isn't caught before the valve dumps on its own.
- The enclosure heater tripped or the space cold, discovered only after ice at the clapper false-trips the valve and floods the system.
- Priming water level never checked, so water backs over the clapper seat and the valve either weeps through or trips low.
- Trip test run but the trip time and water-delivery time never recorded against prior years, so a slowing valve or a fouled quick-opening device trends invisibly.
- System reset and left in service before the low point drains are confirmed clear, so trapped water sits to freeze at the next cold snap.
- The technician's report filed but nothing dated on the building side, so the site can't show the AHJ when the valve was last tripped.
Common questions
- Which dry-pipe sprinkler valve maintenance rounds do these checklists cover?
- Dry-pipe sprinkler valve quarterly maintenance checklist (quarterly): Every quarter, and watched most closely heading into cold weather since the enclosure heat is what keeps the valve from freezing and false-tripping. Dry-pipe sprinkler valve annual maintenance checklist (annual): Once a year, coordinated with the technician and the monitoring station placed on test, timed so the system can be dried, reset and returned to service the same day.
- Who runs the dry-pipe sprinkler valve maintenance round?
- The building engineer or sprinkler service tech reading the gauges and the enclosure on the quarterly round, recording conditions rather than tripping the valve. The facilities lead witnessing the sprinkler technician's annual trip test and recording the observed times and pressures, while the technician performs the test and resets the valve.

- Which standards is dry-pipe sprinkler valve work verified against?
- NFPA 13, published by the National Fire Protection Association; NFPA 25, published by the National Fire Protection Association. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (11 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
